Water at 100 kPa and 400 K is heated electrically, adding 700 kJ/kg in a constant pressure process. Find the final temperature using-
a) The ideal gas table A-8 (Ideal gas properties of various substances, Entropies at 0.1 MPa (1-bar) pressure, mass basis)
b) Constant specific heat from table A-5(Properties of various ideal gases at 250C, 100 kPa)
- Also find the specific heat at constant pressure for water at a temperature of 400 K using Table A-6(Constant-Pressure specific heats of various Ideal gases)
